Abstract : From detonation of this bomb at the particular height used, it can be concluded that minimum horizontal range at which small, rugged, well built equipments with little shielding will remain operable is between 500 and 800 yards. Large sets of the SCR-3999, SCR-584 class remain operative, especially with minor shielding, at 1200 to 1500 yards. Precision radar at this distance will need mechanical reorientation before accurate fire-control can be resumed. Medium size equipment will be little affected at ranges intermediate between those stated above. Major damage at the Able Test was blast inflicted with the heat flash producing less serious effects.
